What is whey protein?

Before learning about the 5 best Whey proteins of 2025, we need to understand exactly what Whey protein is and its properties. Whey protein, also known as “Whey protein” or Whey protein, is a supplement (although it could almost be considered a food) obtained from milk whey. It is an excellent source of high-quality proteins with high biological value, making its bioavailability (the body's availability to use those nutrients) very high.

Types of Whey protein

In addition, you will be able to find it in different formulations, each adapted to your context and situation.

Whey protein concentrate, ideal for people who do not have any intolerance or want to start consuming it for the first time, ideal for ensuring proper recovery.
Whey protein isolate: This protein is intended for people who are lactose intolerant or who do not tolerate it very well. Through the Cross-Flow Microfiltration (CFM) the lactose is removed, along with some of the fat it may contain.
Hydrolyzed Whey Protein, specifically for people with serious digestive problems or older populations; the hydrolysis process makes the protein “predigested,” so its absorption and digestion are faster.

Why choose Whey protein?

A quality Whey protein has a series of characteristics that make it a safe choice when we seek to maximize results and boost recovery.

You will need to consider the following points when choosing a supplement.

Quality protein seal

A distinguishing quality seal for choosing one of the 5 best Whey proteins of 2025, as it guarantees us a quality and safe product; in this case, Lacprodan® is a certificate that guarantees:

That the the amount of protein on the label is what the product contains.
It is authorized by the European Food Safety Authority (EFSA) for use with athletes within the EU.
Useful in medical and infant nutrition with the corresponding authorizations from the Food and Drug Administration (FDA).
Contains β-lactoglobulin pure, a protein with high biological value.

Lacprodan quality seal Masmusculo Whey protein

Amount of amino acids

Masmusculo's Whey protein has a very complete amino acid profile, especially in leucine (more than 3 g per serving). This promotes muscle protein synthesis and recovery. (Deeth & Bansal, 2019)

Digestive enzymes

It also contains an enzyme complex (DigeZyme®) that combines 5 types of digestive enzymes that are key to:

Improve protein digestion.
Facilitate and promote nutrient absorption.
It makes it suitable for people with lactose intolerance, thanks to its lactase content.
It is free from allergens, making it completely its consumption is completely safe if you have any intolerance or allergy.
Keeps the stomach under healthy conditions, enhancing nutrient availability.

Thanks to the combination of these 3 key points, you can obtain a high-quality protein with antioxidant properties that supports muscle recovery and offers digestibility for rapid absorption without discomfort. This is crucial when selecting the 5 best whey proteins of 2025

Who can take it?

Young people

The quantity and quality of protein, as well as its source, can influence growth, the risk of obesity, and the overall quality of the diet.

Therefore, according to several prestigious organizations and associations such as Academy of Nutrition and Dietetics, Dietitians of Canada (DC), and the American College of Sports Medicine American College of Sports Medicine (ACSM) recommends an intake of between 1.2–2.0 g/kg to promote:

Metabolic adaptation (Thomas et al., 2016)
Protein repair, remodeling, and turnover. (Thomas et al., 2016)

Athletes

Adequate protein intake is essential for athletes to:

Maintain and develop muscle mass.
Optimize recovery
Improve performance

The recommendations are similar to those for other populations (1.2–2.0 g/kg), although some studies (Phillips & Van Loon, 2011) indicate that during periods of calorie restriction or very intense training, it may be beneficial to increase this amount to 2.3 g/kg, with the aim of preserving as much muscle mass as possible.

In addition, distributing protein intake throughout the day and choosing high-quality sources (rich in essential amino acids such as leucine) are key factors in maximizing muscle protein synthesis, enhancing athletes’ recovery and performance. (Murphy et al., 2015).

Older people

Consuming this supplement is particularly beneficial for older people due to its many benefits. (Baum et al., 2016) (Landi et al., 2016) :

Maintenance of muscle mass
Maintenance of strength and functionality
Prevents sarcopenia (age-related loss of muscle mass).
Reduces frailty associated with aging.

The recommended intake for the general population is 0.8 g/kg, which is insufficient for this population group because they have a lower anabolic (muscle-building) response when protein doses are lower. (Bauer et al., 2013).

This means that they need to consume higher amounts; studies have shown that between 1.0 g/kg and 1.5 g/kg per day is more than adequate to preserve muscle mass, especially when combined with strength training. (Coelho-Júnior et al., 2018; Park et al., 2018)

Is it necessary to train to take it?

Most of the time, whey protein consumption is associated with a very specific type of person, leading people to think that only those who train can take it.

Nothing could be further from the truth; it is not necessary to train in order to consume it, although it is true that its effects are maximized when combined with strength training. Whey protein can be a very healthy option, and you can also make a wide variety of recipes with it (pancakes, mousse, smoothies, cookies…) and add a different flavor to your dishes without giving up what you like.

Benefits of whey protein

Adequate consumption of this supplement offers multiple health benefits, especially when exceeding the recommended 0.8 g/kg and combining it with strength training, achieving (Carbone & Pasiakos, 2019; Leidy et al., 2015; Paddon-Jones et al., 2008):

Preserving muscle mass during weight loss
Improving blood glucose control.
Facilitating body weight management.
Increasing satiety and energy expenditure.

In fact, in older adults, its consumption has some added benefits that help counter aging, such as:

Reducing the risk of fractures (Rizzoli et al., 2018)2018).
Maintaining bone mineral density (in combination with calcium) (Rizzoli et al., 2018)2018).
Improved strength, muscle mass, and physical performance when combined with training (Ten Haaf et al., 2019).

Therefore, a diet with sufficient protein, distributed throughout the day and combined with physical activity, is key to muscular, bone, and metabolic health throughout life (Pasiakos, 2015)2015).

Which protein should I consume? The 5 best whey proteins of 2025

Of all the brands, formulations, and types of whey protein available, you will be able to find out which are the 5 best whey proteins of 2025 for you and, above all, why.

1. Moremuscle Whey Protein 80, the combination of quality certifications such as Lacprodan® y DigeZyme®, along with others such as GMP, ensure a quality product. It features more than 3 g of leucine per serving and more than 20 different flavors.

2. Life Pro Whey Protein contains quality certifications for its raw materials, such as Lacprodan®, although it is only enriched with the lactase enzyme.

3. Only Whey by Big, like the previous brand, uses high-quality Lacprodan® raw materials; it is enriched with the lactase enzyme, but has a more limited variety of flavors and a higher price.

4. Whey 80 Professional by IO.Genix: combines DigeZyme® with the Lactomin® patent as a raw material source, and is also enriched with vitamin B6.

5. Predator Protein by Amix contains DigeZyme® as an added enzyme complex and is sweetened with Splenda® sucralose; however, it does not have quality certifications for the raw materials it uses. This places it in this position.

Doses and timing

Although the minimum recommended dose is 0.8 g/kg, consuming more than 1 g/kg is recommended to promote and maximize gains in muscle mass and strength. The amount varies according to the level of physical activity. (Schoenfeld & Aragon, 2018; Wu, 2016):

Light activity: 1.0 – 1.2 g/kg
Moderate activity: 1.3 – 1.4 g/kg
Intense activity: 1.6 g/kg or more

When should we consume it?

It is advisable to distribute total protein intake throughout the day across several servings (at least four), with the aim of optimizing muscle protein synthesis. Scientific evidence (Schoenfeld & Aragon, 2018; Smeuninx et al., 2020) suggests 0.4 g/kg per meal or serving.

This would be equivalent to around 25 g of protein for a 60 kg person, or around 32 g for an 80 kg person. Even so, if you are going to consume protein and do not want to do the calculations, Moremuscle’s Whey Protein provides ~ 20–25 g per serving, supporting the activation of protein synthesis. (Areta et al., 2013)2013).

Quantity: is more better?

For healthy people, chronic consumption of up to 2 g/kg/day is safe, and the tolerable upper limit is 3.5 g/kg/day, although doses above 2 g/kg/day may be associated with digestive, kidney, or vascular problems and should be avoided over an extended period. (Schoenfeld & Aragon, 2018; Wu, 2016)2016).

Only shakes? Different ways to consume the 5 best Whey proteins of 2025.

Traditionally, consuming Whey Protein has been associated with having a shake in the gym locker room, and it is indeed one way to consume it; however, you will be able to discover a wide variety of options you may not have known about:

Protein Pancakes, appealing during fat-loss periods because of the satiety they provide.
High-protein cookies, a great snack to eat at any time of day; they are also healthier and high in protein.
Protein yogurt: Mix natural yogurt with Whey protein and fruit; add granola or another cereal if you need more calories or carbohydrates.
Rice cream with protein; this combination is ideal in many situations, before or after training, with high-calorie diets, or as a substitute for a main meal away from home.
Protein and fruit ice cream, a perfect combination for summer.

Supplement combination to maximize results.

By combining whey protein with other supplements, we can improve results, boosting recovery and its effects. Some supplements you can use for this are:

Creatine monohydrate, combined with protein, will enhance your muscle mass and strength gains.
Rice cream; when we combine both, we get a meal rich in easily digestible and rapidly absorbed carbohydrates and protein, providing an ideal pre- or post-workout option.
Fat burners: when we want to lose fat and maintain proper nutrition and training, fat burners like Lucifer can help us mobilize those stubborn areas. Combined with protein, they create good synergy, as protein will help us maintain muscle mass in optimal condition.
